Description
本発明は、空気浄化の技術分野、特にセントラル空調用の殺ウイルス及び滅菌装置に関する。 The present invention relates to the technical field of air purification, in particular a virus-killing and sterilizing device for central air conditioning.
セントラル空調換気システム内の汚れたほこりは、ウイルスや細菌のキャリアとして、セントラル空調システムを介して人々が移動する屋内の場所に病原体を拡散させ、それによって空気伝染による呼吸器感染症の流行または発生を引き起こす。また、換気ダクト内の粒子状物質、冷却塔や加湿器から発生する微生物エアロゾル、空調用ダストフィルターの表面に付着したダストマイトなども、オフィスビルの密集したオフィススペースに拡散しやすく、人の健康を脅かす。 Dirty dust in the central air-conditioning ventilation system, as a carrier of viruses and bacteria, spreads pathogens to indoor locations where people move through the central air-conditioning system, thereby causing epidemics or outbreaks of respiratory infections due to airborne infections. cause. In addition, particulate matter in ventilation ducts, microbial aerosols generated from cooling towers and humidifiers, dust mite adhering to the surface of air conditioning dust filters, etc. can easily diffuse into the dense office space of office buildings, improving human health. threaten.
従来の屋内ウイルス消毒殺菌方法には、スプレー消毒液、紫外線ランプ、空気清浄機などがある。セントラル空調で使用される空気浄化および消毒装置は、多くの場合、プラズマナノ光触媒方法を使用して空気を浄化し、その原理は、浄化装置の電極板上に二酸化チタン（ＴｉＯ２）ナノ材料を調製して、高い比表面積と高い酸化性を備えた二酸化チタンフィルムを形成し、低温プラズマの放電によって生成される紫外線波長（３５０－４００ｎｍ）を利用して、励起による高性能活物質を生成し、プラズマ自体のヒドロキシルラジカルと結合して、複合触媒酸化効果を生み出すことである。この種の装置は構造が複雑で、空気中の大きな浮遊粒子に対して、優れた浄化効果があるが、空気中にウイルスを含む非常に小さなエアロゾル浮遊物を効率的に殺すことができない。また、装置全体が非常に複雑で専門的なメンテナンスが必要であり、使用時間の延長とともに、その空気清浄、殺ウイルス及び滅菌効果も低下になる。 Conventional indoor virus disinfection and sterilization methods include spray disinfectants, ultraviolet lamps, and air purifiers. Air purification and disinfection equipment used in central air conditioning often purifies air using plasma nanophotocatalytic methods, the principle of which is to prepare titanium dioxide (TiO2) nanomaterials on the electrode plate of the purification equipment. Then, a titanium dioxide film having a high specific surface area and high oxidizing property is formed, and a high-performance active material by excitation is produced by utilizing the ultraviolet wavelength (350-400 nm) generated by the discharge of low-temperature plasma. It combines with the hydroxyl radicals of the plasma itself to produce a composite catalytic oxidation effect. This type of device has a complex structure and has an excellent purifying effect on large suspended particles in the air, but cannot efficiently kill very small aerosol suspended matter containing viruses in the air. In addition, the entire device is very complicated and requires specialized maintenance, and as the usage time is extended, its air cleaning, virus killing and sterilization effects are reduced.
現在、家族で一般的に使用されている屋内ウイルス消毒殺菌装置には、紫外線ランプと空気清浄機が含まれている。紫外線ランプは、水銀ランプにより放射された紫外線を利用して殺菌・消毒機能を実現し、この放射された紫外線は、エネルギーが大きく、保護対策がないと人体に大きな害を及ぼしやすくなり、また、紫外線ランプにより、オゾンなどの二次汚染も発生する可能性があるため、夜間で人がいない状態で使用されることが多く、２４時間無休で動作することはできない。現在市販されているウイルス消毒殺菌機能を備えた空気清浄機は、通常、プラズマ浄化技術や強力なフィルターなどを使用している。この方法は、空気中の大きな浮遊粒子にのみ適しており、浄化効率が低い、混雑した大規模なオフィスにある場合、その空気清浄、殺ウイルス及び滅菌効果は非常に低く、セントラル空調に適していない。 Currently, indoor virus disinfectant sterilizers commonly used by families include UV lamps and air purifiers. The ultraviolet lamp realizes the sterilization and disinfection function by using the ultraviolet rays emitted by the mercury lamp, and the emitted ultraviolet rays have a large energy and are likely to cause great harm to the human body if there is no protective measure. Since the ultraviolet lamp may also generate secondary contamination such as ozone, it is often used in the absence of people at night and cannot operate 24 hours a day, 7 days a week. Currently available air purifiers with virus disinfection and sterilization functions usually use plasma purification technology or powerful filters. This method is only suitable for large suspended particles in the air, and its air cleaning, virus killing and sterilization effects are very low when in a large, crowded office with low purification efficiency, making it suitable for central air conditioning. do not have.
殺ウイルス及び滅菌効果が高く、セントラル空調に適した殺ウイルス及び滅菌装置をどのように提供するかが、早急に解決すべき技術的課題となっている。 How to provide a virus-killing and sterilizing device that has a high virus-killing and sterilizing effect and is suitable for central air conditioning is a technical issue to be solved immediately.

４．該装置は、紫外光吸収体を使用して過剰な紫外光を熱エネルギーに変換し、空冷装置または水冷装置によって除去され、構造がシンプルである。
The technical effects of the present invention are as follows.
1. 1. It has been proposed to use UV laser light instead of traditional UV laser lamps, which has a simple structure, does not generate secondary contaminants such as ozone, and the energy of UV laser light is conventional. Since it is tens of millions of times larger than an ultraviolet lamp, it can instantly kill pollutants such as viruses, and is extremely excellent in virus killing and sterilization effects.
2.2 Two sets of reflectors are used to reflect UV laser light back and forth to increase the duration of action of muddy air and UV laser light, gradually kill pollutants in the air, kill viruses and sterilize. Further improve the efficiency of. The number of reflections can be adjusted by adjusting the incident angle β of the ultraviolet laser beam.
3. 3. The device does not require a structure such as a filter, has almost no effect on the air duct, and has no air resistance, so that the energy consumption of the central air conditioning is saved and the usage cost is reduced.
4. The device uses an ultraviolet light absorber to convert excess ultraviolet light into heat energy, which is removed by an air cooling device or a water cooling device, and has a simple structure.
従来の紫外線ランプと比較して、紫外線レーザー光のエネルギーは紫外線ランプのそれより数千万倍高く、そして、紫外線レーザー光と空気の相互作用は、オゾンなどの二次汚染物質を生成せず、紫外線レーザー光は指向性に優れている。紫外線レーザー光は該装置内で最終的に吸収体に完全に吸収され、オーバーフローして人体に害を及ぼすことはないため、該装置は一日中途切れることなく動作できる。 Compared to conventional UV lamps, the energy of UV laser light is tens of millions of times higher than that of UV lamps, and the interaction between UV laser light and air does not produce secondary contaminants such as ozone. Ultraviolet laser light has excellent directivity. The UV laser beam is finally completely absorbed by the absorber in the device and does not overflow and harm the human body, so that the device can operate without interruption throughout the day.
ウイルス消毒殺菌機能を備えた空気清浄機に比べ、該装置は、構造がシンプルで、空気中の極小の細菌やウイルスを浄化でき、浄化効率が高く、後で洗浄して交換する必要のある分離ネット等の設備がなく、メンテナンスコストが低い。 Compared to an air purifier with virus disinfection and sterilization function, the device has a simple structure, can purify tiny bacteria and viruses in the air, has high purification efficiency, and needs to be cleaned and replaced later. There is no equipment such as a net, and maintenance costs are low.
セントラル空調に使用される空気浄化・消毒装置と比較して、この装置は複雑な触媒装置を備えず、２組の平行反射鏡を使用して紫外線レーザー光カーテンを前後に反射および重ねさせる。これにより、汚染された空気が紫外線レーザー光と相互作用する時間が長くなる。この方法は、微細な粒径を有するウイルスエアロゾルを殺滅する問題を解決することができる。また、紫外線レーザー光の入射角を調整し、反射回数を増加させることにより、高効率の滅殺の目的を達成する。同時に、この装置の追加は、セントラル空調の元のエアダクト構造を変更せず、空気抵抗を追加せず、空調のエネルギー消費をほとんど増加させない。２４時間中断することなく動作でき、オゾンなどの二次汚染物質を生成することはない。装置全体がシンプルな構造で、既存ビルのセントラル空調に使用でき、セントラル空調の給気管部に設置すればよい。また、使用時間の延長により、該装置のウイルスを殺滅する能力はほとんど低下しない。 Compared to the air purification and disinfection equipment used in central air conditioning, this equipment does not have a complex catalytic device and uses two sets of parallel reflectors to reflect and overlay the UV laser light curtain back and forth. This prolongs the time that the polluted air interacts with the UV laser light. This method can solve the problem of killing viral aerosols with fine particle size. In addition, by adjusting the incident angle of the ultraviolet laser beam and increasing the number of reflections, the purpose of highly efficient extermination is achieved. At the same time, the addition of this device does not change the original air duct structure of the central air conditioning, does not add air resistance, and hardly increases the energy consumption of the air conditioning. It can operate uninterrupted for 24 hours and does not produce secondary contaminants such as ozone. The entire device has a simple structure and can be used for central air conditioning in existing buildings, and can be installed in the air supply pipe section of central air conditioning. In addition, the extended use time does not significantly reduce the ability of the device to kill the virus.
